To all whom it may concern/:f a Be it known that we, WILLIAM V.

GOTT and HENRY OHARA, both ofthe city of St. Louis, inthe StateOfMissouri, have .in- `vented a certain new and useful Im`prove`` mentin Car-Couplers, ofwhich the' following l is afull, clear, and exactdescription, reference being .had 4to the accompanying draw- \ings,forming part of this specification. l n `Our invention relates tocertain improvements imautomatic car couplers, ofthe class Shown,described `and ,claimed inthe `patent issued to the Keystone Car CouplerCompany, dated November19`,18S9,-No. 415,309, and the `reissue patent toLorraine and Aubin,"No.` 10,941, dated 'J une 26, 1888. y a a Ourinvention consists in features of novelty hereinafter fully describedand pointed out in the claims. n a.w` Figure I is a plan view ofone ofthe drawheads, showing the hook in its closed or using position. Fig. IIis a horizontal section, taken on line II-II,`Fig. III, and showing thehook in its open position. Fig. III isV an end view of one of thedraw-heads,lwith thecoupling hook removed, and showing the trunnionbearings and abutment; also the ledges inside of the draw-head near thefront end. Fig.' IV isa side view, part in section, showing the positionof the hook when locked in the draw-head, also the position of the pineX- tending down through the perforated trunnions, also the perforationin the coupling hook, also the rib ,on the upperl side of the inner armthat guides thelooking pin, also the ledges in' the drawhead, and alsothe rib on the lowerside of the inner arm of the coupling hook. Fig. Visavertical section,taken on line VV, Fig. I, and showing the position ofthe pin in the perforated trunnion bearings, and also the hook andposition of the trunnion bearing in the perforated recess coupling hook.Fig. VI `isa detail seotion,A showing the abutment` and coupling hookwhen closed and locked, ready for tran-` sit. Fig. VII is a similarview, showingthe coupling hook when in its opened position. Fig. VIII isa section taken on line VIII- VIII, Fig. IX, showing the hook in topview and in its locked position, and showing its relation and bearingson the perforated trun- WOL? i locking pin; a the hook removed from thedraw-head. Fig.

`of the drawheads, and 2 one of the hooks of closed, and a lower rib 9.

flanges fitting against the trunnion nion.` Fig. IXisa section takenonline IXV IX, Fig; VIII and showing the positionof the inner arm of thehook withrelation to the Fig. X is a perspective viewof '55 XI is aperspective viewof the lower `half of onefof the 'drawheads i Referringto the drawings,l represents one 6o an automatic car coupler, intendedto con` nect with a draw-head and hook correspondingly formed. "Ilhehook has a perforated hub 3 having a recess 4i at each end, forming 6represents the inner arm of the hook having an upper rib 7, beyond whichis a table portion 8 on which the lower end of the locking pin rides asthe hook` is opened and The drawhead is provided with perforated 7trunnion bearings 10 between which the hub 3 tits, as shown clearly inFig. V, and ll represents abutments extending from the trun-` nionbearings to the' vertical wall 12 of the draw-head, (seeFig. XI.) tWhenthehook is in place` a pin 13 is passed through the perforated huband trunnion bearings, and the flanges 5 fit against the verticalfaces14 of thetrunnion bearings and limit the opening 8o and closing movementof the hook by their ends 15 impinging, respectively, against the innerand outer vertical faces of the abut- 4ments` 11, see Figs. VI and VII.yThese n bearings, 85 take all strain off the pin 13 when the hook is inits `closed or using position, as will be clearly seen in Figs. VI andVIII, andthey Valso serve as an additional bearing surface locks thehook. As the hook opens and roo y closes the outer vertical walls of theribs 7 and 9 bear against the inner vertical walls of a ledges 17 in thedraw-head, Which assists in the guiding of the hook, and, When the hookis in use, affords strength and rigidity to the parts. v

We claim as our inventionl. In a car coupler, the combination ofvacoupling hook, and a draw-head provided with perforated trunnionbearings reinforced by an abutment extending from the perpendicular Wallof the drawhead to the trunnion bearing; and in combination therewith,of a common gravity vertical moving locking pin,

resting upon theinner arm of the hook, when open, and riding on saidinner arm When the hook is being closed.

2. In acar coupler, the combination of a coupling hook provided with aperforated and recessed hub and ribs on its inner arm, and a dravvheadprovided with perforated trunnion bearings connected by abutmentsextendingto the perpendicular Wall of the drawhead, ledges in the throatof the draw head, and a gravity vertical moving locking pin, restingupon the inner arm of the coupling hook when open, and riding upon saidarm when the hook is closing.

3. In a car coupler, the combination of a coupling hook, provided with aperforated recessed hub, ribs on theinner arm of the hook, and adrawhead provided with perforated trunnion bearings connected byabutments to the perpendicular Wall of the drawhead, ledges in thethroat of the drawhead, a pin passing through the perforation in thetrunnion bearings, and a perforation inthe coupling hook hub, and agravity vertical moving locking pin resting entirely upon the inner armof the coupling hook when open, and riding on said arm When the hook isbeing closed.
